✦ Synopsis

An Easy and Efficient Synthesis of 3-Nitrochromans. -The reaction of nitro olefins (II) with (I) in the presence of DABCO generates 3-nitrochromans (III) with a high stereoselectivity. Interestingly, the sam nitrochroman is formed from both the (E)-nitroolefin and from the corresponding (Z)-isomer indicating a stepwise mechanism. -

## Abstract 3′‐Amino‐3′‐deoxyguanosine was synthesized from guanosine in eight steps and 58% overall yield. The 2′,3′‐diol of 5′‐__O__‐[(__tert__‐butyl)diphenylsilyl]‐2‐__N__‐[(dimethylamino)methylidene]guanosine was reacted with __α__‐acetoxyisobutyryl bromide and treated with 0.5n NH~3~ in MeOH t
